Having tlius described my invention in its referred form of construction and usefulness, I desire it understood tliat same may be variously changed and modified Without departing from the spirit ofmy invention as liereinafter claimed. I Neither do l limit myself to the packing of joints in a pipe-organ, since tlie invention is equally effective in simil arly packing pressure-joints in general7 especially orted pressure-joints,regardless of Whether 'the fluid employed is air, steam, or gas.

Vliat l now claim, and desire to secure by Letters Patent, is-'- l, The combination With adjacent members of a pressure-joint, of an outlet-port in at least one of said members7 and a self-acting packing for said joint comprising a ported exible membrane secured around said outlet-port and adapted to be flexed by pressure from Witliin, substantially as described.

2. The combination with adjacent members of a pressureejoint, of an outlet-port in at least one of said members, and a self-acting packing for said joint comprising a ported flexible membrane secured by its edges around said outlet-port and adapted to be exed by pressure from Within, substantially as described.

3. The combination With adjacent members of a pressure-joint, of an outlet-port in at least one of said members, and a self-acting packing for said joint comprising a ported iiexible membrane in concentric arrangement with relation to said outlet-port and adapted to be flexed by pressure from Within, substantially as described.

4. The combination with adjacent members of a pressure-joint, of an outlet-port in at least one of said members, a self-acting packing for said joint comprising a ported exible membrane secured around said outletport, and an air-pocket adjacent to said membrane in direct communication with the outlet-port aforesaid, substantially as described.

5. The combination with adjacent members of a pressure-joint, of an outlet-port in at least one of said members, a self-acting packing for said joint comprising a ported flexible membrane secured around said outlet-port, and an air-pocket adjacent to said membrane in register Witli tlie port aforesaid but of larger diameter, substantially as described.
